The clinical success rates of SEMS and TDT were 88 and 90%, respectively (p = 1.0). The cfDNA concentration on day 7 was significantly higher in the SEMS group than in the TDT group (992 vs. 308 ng/mL; p = 0.005). A significant increase in ctDNA was observed in the SEMS group compared with the TDT group (83% vs. 22%; p = 0.002). The cfDNA concentration showed strong positive correlations with ctDNA and lactate dehydrogenase (R2 = 0.838 and 0.593, respectively), and a weak positive correlation with C-reactive protein (R2 = 0.263).
